THREAD GUIDE FOR SPINNING MACHINES Original No. 1,500,258, dated July 8,1924, SeriaLNo. 676,752, filed November 24, 1923. Application forreissue filed January 21,

This invention has reference to guides for wlndlng or spinningmachlnes,where a thread is drawn from one spool or bobbin and wound uponanother spool. 1

The object ofthe present invention is to provide a thread guide thatwill have its portion adapted to engage a thread of considerable extentor area, and which member can be readily shifted or adjusted whereby aconsiderable number of different surfaces can be brought to position forengagement with the thread,'and by a comparatively small and simpleadjustment on the support for the guide member.

A further object of the invention is to provide a special guide arm toprevent the thread movement away from its desired engaging osition, andwhich member is also made adustable to be shifted corresponding with theshifting movement of the thread engaging portion. v

In the accompanying drawing showing one embodiment of my invention,

Fig. 1 is a side elevation of the device.

Fig. 2 is a longitudinal section.

Fig. 3 is a transverse section.

Fig. 4 is a similar view showing Wear in I the disc by the thread.

Fig. 5 shows a modified form of the device with the guide or threadretainer, in side elevation.

Fig. 6 is a transverse section device as shown in Fig. 5. 'In theuseofsuch devices as these, especially where the memberthat engages thethread is formed of a non-metallic substance such as porcelain, it isfound that the friction of the thread passing against the guidesurthrough the Serial No. 82,831.

ment, and without shifting the supporting member.

In the arrangement shown herein I provide a support in the form of adisc or spool 7 that is adjustably carried by a supporting member in theform of a rod or stem 8. The disc is shown as provided with acomparatively deep annular groove 9. The disc is provided with a bore10, into which projects the end portion 12 of the stem, that is bent toextend at a right angle to the stem 8. This bent portion is passedthrough the bore of the spool, and the extremity is provided with asuitable fastening means, such as a nut 13 en gaging the screw threadextremity 14; of the stem. It will be understood that when this nutistightened against the side face 15 of the spool, the latter will bepressed on the bent portion of the stem until the opposite face 15' ofthe spool will engage the stem 8.

Upon loosening the nut 13 the spool can obviously be turned on the bentstem and a different portion of the grove 9 will be brought to the pathof movement of the thread 6, as indicated in Figs. 3 and 4, where asshown in Fig. 4 the shaded portion 4; represents a worn portion of thespool groove, that by slightly turning the spool will cause a freshunworn part to engage the thread 6, and the nut 13 is again tightened tosecure the spool in this position.

While such an arrangement would provide a considerable number ofadjustments for the spool on the stem, I preferably provide abutmentportions on the spool for engagement with the stem. As shown the spoolon the side 15 is provided with a series of projections forming notchesor radial groves 16', of a size to fit the stem 8 that is brought toregistertherewith as indicated in Fig. 2. As shown I provideeight ofthese radial grooves that will give eight different positions ofadjustment for the spool on the stem and which will be equally spacedapart. When any one place becomes worn by the thread 6 the nut 13 isloosened and the spool slightly vmoved to bring the groove away from thestem 8, and then the spool is turned to bring an adjacent groove 16opposite the stem, when the nut is again tightened. Each fresh surfaceof the spool groove is in the same position relative to the path of thethread 6.

It is further desirable to provide a kind of guide or retainer for thethread to prevent its getting out of the spool groove. In Figs. 5 and 6I show a guide formed by a rod 20 having a loop 21 adapted to be clampedbetween the nut 13 and the adjacent face of the spool, as clearly shownin Fig. 6. The end portion 22 of the guide extends transversely acrossthe plane of the spool, and also that of the stem 8, as indicated inFig. 6. This member and the stem 8 will prevent the thread from movingout of the groove. lVhen the nut is loosened to adjust the spool on thestem, the guide arm can also be shifted to retain it in proximity to thestem. The side 15 of the spool may also be provided with a series ofprojectors forming notches or radial grooves 23 arranged to engage thestem 20, and which grooves are an ranged similar to the grooves 16 onthe op posite side. lVhen the spool is shifted en the stem to engageanother groove with the stem, the guide arm is also shifted in a similarmanner, to engage the next groove, and will thus maintain its positionrelative to the supperting stem 8.

It will be noted, by referring to Fig. 5, that the retainer 20 isangularly bent, so'that the extension 22 thereof overlies the supportingstem 8 permitting the ready introduction of thread therein by a sidewisemotion of the thread. In order to accommodate the desired angularrelation of the retainer to the supporting stem in the grooves 16 onopposite sides of the guide 7 the said grooves are spaced in staggeredrelation to each other on opposite sides and they therefore maintain theretainer and support rod 8 in the desired relation.
